ByteDance launched Seedance 2.0, an AI video generation model that produces 20-second clips with improved motion realism, physics simulation, and prompt adherence. Built on a Diffusion Transformer architecture, it competes with Sora, Veo, and Runway Gen-4. Currently accessible through Doubao and Jimeng AI platforms in China with expanding international availability, though public API access is not yet available. The model represents a significant quality threshold for production use cases in content platforms, marketing automation, and creative tools.
